I have recently gotten a dirt cheap computer. $549 (Australian) with this and a 19"" monitor. I would like to upgrade it in the near future and these are the specs. * AMD Sempron (M) 3800+ 2.2 GHz * GeForce 6150SE nForce 430 Chip set * 512MB DDR2 SDRAM PC2-5300 (Upgradeable to 4 GB) * 80 GB SATA Hdd * 16x DVD +/- R/RW LightScribe Drive * Integrated Video Card * Integrated High Def Sound (ALC 888S chipset) * Integrated Network Port * 56K bps data/fax modem * Memory Card Reader (Supports Most Cards) * Microsoft Windows Vista Basic Pre Installed * Keyboard & Mouse I have already gotten another 2GB of RAM (dirt cheap again) so that Vista would work properly. I was thinking of purchasing one of these AM2 x2 4800+/5000+/5200+ (105/124/133). I also want to upgrade my graphics card so any help will be thankful.
